UNEP's mission is "To provide leadership and encourage partnership in caring for the environment by inspiring, informing, and enabling nations and peoples to improve their quality of life without compromising that of future generations."[3]

SEFI is the UNEP Sustainable Energy Finance Initiative - a platform providing financiers with the tools, support, and global network needed to conceive and manage investments in the complex and rapidly changing marketplace for clean energy technologies.

SEFI's goal is to foster investment in sustainable energy projects by providing up-to-date investor information, facilitating deal origination, developing partnerships, and creating the momentum needed to shift sustainable energy from the margins of energy supply to the mainstream.
